The "stalactites" found on the ancient city walls of the Ming Dynasty are still a mystery.

This happened on the ancient city wall of Nanjing in the last two years, and there are some stalactites found in caves. Experts have not given the answer yet, so we need to explore.

Nanjing is a very famous city with many ancient city walls. Recently, stalactites appeared on a section of the ancient Ming Dynasty city wall, which attracted many people's attention and even came to visit. Because our understanding of stalactites is that they only exist in some caves. There are caves on many mountains in our country. The "stalactites" painted by colorful lights in the cave are very beautiful, and almost all people who like to travel have seen them, but it is the first time to see stalactites on this wall.

Now, the official has not given a real answer to this strange phenomenon, and experts are studying it, but there is a widespread saying that the former city wall was made of glutinous rice juice, but now it has overflowed. Some scholars believe that the Nanjing city wall is based on granite, and then the brick joints are filled with tung oil and glutinous rice juice, so it is so strong. However, according to the Daming Hui Dian, there is no sticky rice juice in the bonding material for the construction of Nanjing City Wall.

There are still many experts who want to know the composition of this adhesive material through various advanced methods, but there is still no good result. Some even use modern advanced scientific and technological means to analyze, and the results can only interpret inorganic components, but can not determine organic components. Therefore, whether the bonding material of Nanjing Ming City Wall contains glutinous rice juice needs further study.

However, it is worth mentioning that the first person to discover the strange sights in the city is not the residents nearby, but people who like photography and travel. It seems that everyone needs a pair of eyes that are good at observing beauty.
